WMNGER-ROLL Application filed April 3,

To all whom it may concern:

Be it known that I, WILLIAM H. Voss, a citizen of the United States, residing at Davenport, in the county ofScott and State of Iowa, have invented certain new and useful Improvements in wringer-Roll Constructions, of which the following is a specification.

My invention relates in general to the construction of wringer rolls and more particularly to the securing of better rolls and economy in manufacture.

Among the objects of my invention are to provide means for using a smaller sized wringer roll rod or shaft than has been customary and yet use the same amount or less of rubber for the same size roll; to provide means for preventing the rubber of the wringer roll from slipping around or along the bar; to reduce the labor and expense incident to turning down the wrin er roll bar or shaft by eliminating this step 1n the process of manufacture; to eliminate the waste caused by the turning down of the shaft to reduce the time consumed in the manufacture of wringer rolls; to reduce the amount of necessary money outlay for machinery for the manufacture of such rolls; to enable more rapid production of wringer rolls; and such further objects, advantages and capabilities as will more fully appear hereinafter.

My invention further resides in the combination, construction, and arrangement of parts illustratedin the accompanying drawing; and while I have shown therein preferred embodiments I desire the same to be understood as illustrative only and not aslimiting my invention.

In the accompanying drawing illustrating my invention Fig. 1 is an elevation of a wringer roll; Fig. 2 is a longitudinal section of the construction shown in Fig. 1; Fig. 3 is a perspective view of the supporting means shown in Fig. 2; Fig. 4 is a longitudi- CONSTRUCTION.

1920. Serial No. 370,988.

Figs. 2 and 3, are preferably made as stampings, while the corresponding structure shown in Figs. 4 and 5 may be made either as stampings or by a casting process. It is, of course, understood that the supporting means 3, 5, may be made by casting if desired and that the supporting means 6, 3, of Figs. 4 and 5, may be made as a tube having no longitudinal slit or having a single one.

I employ a rod or shaft of substantially uniform diameter throughout its length, I eliminate the necessity of turning down the shaft at its ends and, therefore, save time and It will be seen from the above that since labor and decrease waste. It will also be apparent that greater production can be secured and that the amount of money outla for high priced machinery is decrease Furthermore the perforations in the flanges andsleeves prevent the slipping of the rub- @5 her on the shaft and make it easier to vul canize the rubber in place. The end flan es form thrust members to prevent un ue spreading of the rubber, and to prevent wearing of the rubber by contact with the wringer bearing member. The use of the sleeve permits using a smaller shaft without decreasing the diameter of the wringer roll. The use of a sleeve of proper thickness will even permit of the use of a less amount of rubber and, therefore, a reduction in the cost of manufacture. Also, the use of a smaller shaft enables me to use cold rolled steel instead of hot rolled, which reduces the cost of manufacture. Furthermore the cold rolled steel is closer grained and stronger than the hot rolled.

From the above some of the advantages of my construction over prior constructions will be seen.

Having now described my invention, I claim:

1. A wringer roll, a rubber cylinder having a bore, a shaft in said bore, a perforated member secured to said shaft and lying within the bore of said rubber cylinder, said rubher cylinder having portions projecting into the perforations of said member for preventing the relative turning of. said shaft and cylinder.

2. In a wringer roll, a shaft of substantially uniform cross sectional diameter throughout its length, a perforated supporting means secured to said shaft, a rubber cylinder surrounding said shaft and supcylinder and said shaft and supporting means.

3. In a wringer roll, a shaft, a hollow rubber cylinder mounted thereon, means between said shaft and cylinder having flanges to engage the ends of the cylinder, said flanges being rovided with perforations and said rubber aving projections extending into said perforations.

4. In a wringer roll, a shaft, a hollow rubber cylinder mounted thereon, means between said shaftand cylinder having flanges to engage the ends of the cylinder, said means and flanges being provided with perforations and said rubber having projections extending into said perforations.

5. A supporting element of a wringer roll, comprising a shaft of substantially uniform cross sectional diameter throughout the length thereof and a supporting casing secured to the shaft and adapted to support a rubber cylinder, said casing comprising a pair of perforated semi-cylindrical members adapted to be disposed in the bore of said rubber cylinder and provided at their ends with flanges to hold the rubber cylinder and prevent wear vthereof.

In witness whereof, I hereunto subscribe my name to this specification in the presence of two witnesses.

WILLIAM H. VOSS.
